以下命令在本地重命名分支，删除远程位置上的旧分支并推送新分支，设置本地分支跟踪新的远程:

git branch -m old_branch new_branch
git push origin :old_branch
git push --set-upstream origin new_branch

这篇文章展示了如何做到这一点非常简单。

要重命名本地Git分支，我们可以使用Git branch -m命令修改名称: Git branch -m feature1 feature2 如果你只是在寻找重命名远程Git分支的命令，这就是它: Git push -u origin feature2:feature3 在执行此操作之前，请检查分支上是否有标记。你可以用git标签做到这一点。

只需删除旧的分支并创建新的分支。

示例(仅重命名远程分支):

git push origin :refs/heads/oldname
git push origin newname:refs/heads/newname

您可能还应该重命名本地分支，并更改推/拉位置的设置。

下载Atlassian Sourcetree(免费)。 导入存储库的本地克隆。 在侧边栏中右键单击要重命名的分支。从上下文菜单中选择“Rename branch…”，并重命名它。 推到原点。

在GitHub端，您可以使用新的(2021年1月)“支持重命名现有分支”(受保护的分支只能由管理员重命名，见末尾)

跟随本教程:https://docs.github.com/en/github/administering-a-repository/renaming-a-branch

参见“如何在GitHub网站上重命名分支?”。

这是一个更好的方法，因为以这种方式重命名分支(在github.com上)将:

Re-target any open pull requests Update any draft releases based on the branch Move any branch protection rules that explicitly reference the old name Update the branch used to build GitHub Pages, if applicable Show a notice to repository contributors, maintainers, and admins on the repository homepage with instructions to update local copies of the repository Show a notice to contributors who git push to the old branch Redirect web requests for the old branch name to the new branch name Return a "Moved Permanently" response in API requests for the old branch name

2021年12月更新:

Restrict renaming protected branches to admins Now, only admins can rename branches that are protected by branch protection rules. GitHub allows repository collaborators to rename every branch in a repository, with the exception of the default branch. When a collaborator renames a branch, any non-wildcard branch protection rules that apply to that branch are also changed to match the branch's new name. Because only admins can modify branch protection rules, renaming of a protected branch is now limited to admin users. For more information, visit Renaming a branch and Managing a branch protection rule.

在Git本地和远程中重命名分支

1. 重命名您的本地分支。

如果你在你想重命名的分支上:

git branch -m new-name

如果你在不同的分支上:

git branch -m old-name new-name

2. 删除旧名称的远程分支，并推送新名称的本地分支。

git push origin :old-name new-name

3.重置新名称本地分支的上游分支。

切换到分支，然后:

git push origin -u new-name

所以结论是:

git branch -m new-name
git push origin :old-name new-name
git push origin -u new-name
